סימן קנג סעיף יג

כְּשֵׁם שֶׁהִיא אֲסוּרָה לִמְזֹג לוֹ אֶת הַכּוֹס, כָּךְ הוּא אָסוּר לִמְזֹג לָהּ. וְלֹא עוֹד, אֶלָּא אֲפִלּוּ לִשְׁלֹחַ לָהּ כּוֹס יַיִן הַמְיֻחָד לָהּ, אֲפִלּוּ הוּא כּוֹס שֶל בְּרָכָה, אָסוּר.

Just as she is forbidden to pour a cup of wine for you, so are you forbidden to pour wine for her.²²These laws must also be observed at the seder on Pesach. Furthermore, even to send her a cup of wine specially for her, even if it is a cup over which a berachah has been pronounced, is forbidden.²³With regard to wine from Kiddush, if you send her the cup you drank from, in an unusual manner, for instance, with your left hand; she is permitted to drink from it according to Prisha. However, Ya’avetz (Responsa 126) rules even if it is the cup you drank from and did not pour it specially for her, you are still not allowed to send it to her. The best thing to do is to leave the cup in front of you and let her take it herself.
